Thank you. That did confirm I was looking at the wrong spec. I was looking at a 2024 model, whereas yours is a 2023 model.
Your model, FA617NS, comes in three display variants. You might be able to confirm that the top option here, is yours? (it would at least match what xrandr has been presenting). Does your laptop, or laptop box have written on it “FHD+” or “QHD+” anywhere?
You could try adding the kernel parameter @1093i3511 details in the bottom half of this post. It’s to address issues with some TUF Gaming A16 laptops detailed in the Wiki.
Well. FIrst of all I tried this by installing linux-lts and selecting it while booting it, but it was of no use, and actually, the temporary fix I use of changing the refresh rate to 60,01Hz and back to 160,01Hz doesnt work on that kernel version
Well. I tried the part that advises me to add the kernel parameters by running sudo nano /etc/dracut.conf.d/cmdline.conf (it seems this file did not exist before) and adding and saving:
The concerning thing about the Reddit post, is they said that while this fix (the kernel parameter) had worked, more recent updates the kernel seemed to have reintroduced the issue
In my case creating any new files or directories didn’t help either. However I did a thing described below, and it seems to have worked.
What comes to the reintroduction of the issue, I think doing this same thing with inserting a kernel option again might do the trick in the future, but we’ll see. The main point is that nothing has ever helped me before, until this particular thing. Good luck to you, and please tell us if it worked for you as well.
